In both embodiments, the packaging cushioning structure includes a first cushioning body and a second cushioning body. At at least one side of the first cushioning body, the first cushioning body includes a first assembly portion and a first clamping portion connected to the first assembly portion. At at least one side of the second cushioning body, the second cushioning body includes a second assembly portion and a second clamping portion connected to the second assembly portion. In the first embodiment, locking and fastening is implemented through the first clamping portion and the second clamping portion that are a protruding structure and a recessed structure, respectively. In the second embodiment, the first clamping portion and the second clamping portion are recesses, and are locked and fastened through a fastening member.

FIELD OF THE INVENTION

The present invention relates to a cushioning material, and particularly to a cushioning material capable of assembling into any desired size through mutual locking and fastening or using a fastening member.

BACKGROUND OF THE INVENTION

Along with the precision trend of technology products, in order to prevent damages caused by impacts during a transportation process of the products, many manufacturers and industrialists adopt cushioning materials for preventing impacts during packaging and transportation processes. However, most commercially available cushioning materials are designed for small and delicate objects, and are naturally small in size. Thus, most current cushioning materials cannot be applied to provide protection for large objects, e.g., motorcycles and refrigerators. Further, taking a cushioning material applied for a display panel for example, a locking-fastened cushioning material is placed at two sides of the display panel to lock and fasten the two sides of the display panel to further provide protection. Such protection means usually protects only the left and right sides and provides no zero protection for the screen. If the front side of the screen receives an excessive impact, the screen of the display panel is likely damaged. Further, the pattern of conventional cushioning material is fixed after an injection molding process, and cannot be expanded according to application requirements. If the pattern of a product to be protected is slightly modified, a new mold needs to be again manufactured for producing a new cushioning material through injection molding. Costs and time for providing a new mold are extremely high, which result undue costs and time for the cushioning material made through injection molding.

SUMMARY OF THE INVENTION

It is a primary object of the present invention to solve an issue of a conventional cushioning material that is incapable of protecting large objects.

It is a secondary object of the present invention to solve an issue of a conventional cushioning material that is capable of protecting only two sides of an object.

To achieve the above objects, the present invention provides a packaging cushioning structure including a first cushioning body and a second cushioning body. At at least one side of the first cushioning body, the cushioning body includes a first assembly portion and a first clamping portion connected to the first assembly portion. The width of the first assembly portion is smaller than the width of the first clamping portion. The second cushioning body may be spliced with the first cushioning body. At at least one side of the second cushioning body, the second cushioning body includes at least one second assembly portion and a second clamping portion connected to the second assembly portion. The width of the second assembly portion is smaller than the width of the second clamping portion. When the second cushioning body is spliced with the first cushioning body, the second assembly portion locks and fastens the first assembly portion and the second clamping portion locks and fastens the first clamping portion, such that the second assembly body and the first assembly body become secured.

In one embodiment, the first cushioning body includes at least one third assembly portion disposed at a distance from the first assembly portion, and a third clamping portion connected to the third assembly portion. The second cushioning body includes at least one fourth assembly portion disposed at a distance from the second assembly portion, and a fourth clamping portion connected to the fourth assembly portion. The width of the third clamping portion is greater than the width of the third assembly portion, and the width of the fourth clamping portion is greater than the width of the fourth assembly portion.

In one embodiment, the first assembly portion and the third assembly portion have opposite configuration directions, and the second assembly portion and the fourth assembly portion have opposite configuration directions.

To achieve the above objects, the present invention further provides a packaging cushioning structure including a first cushioning body, a second cushioning body and at least one fastening member. At at least one side of the first cushioning body, the first cushioning body includes at least one first assembly portion and a first clamping portion connected to the first assembly portion. The width of the first clamping portion is greater than the width of the first assembly portion. The second cushioning body is disposed correspondingly to the first cushioning body. At one side facing the first cushioning body, the second cushioning body includes at least second assembly portion corresponding to the first assembly portion and a second clamping portion connected to the second assembly portion.

Each of the first cushioning body 1 and the second cushioning body 2 is made of a cushioning material, e.g., corrugated paper, a plastic material or other materials having an appropriate rigidness. Further, at at least one side of the first cushioning body 1, the first cushioning body 1 includes at least one first assembly portion 11 and a first clamping portion 12 connected to the first assembly portion 11. At at least one side of the second cushioning body 2, the second cushioning body 2 includes a second assembly portion 21 and a second clamping portion 22 connected to the second assembly portion 21. The second assembly portion 21 may lock and fasten the first assembly portion 11, and the second clamping portion 22 may lock and fasten the first clamping portion 12, such that the second cushioning body 2 and the first cushioning body 1 become secured. Further, the width of the first assembly portion 11 is smaller than the width of the first clamping portion 12, and the width of the second assembly portion 21 is smaller than the width of the second clamping portion 22, thereby securely locking and fastening the first cushioning body 1 with the second cushioning body 2. Specifically, the width of the first clamping portion 12 and the second clamping portion 22 stands for the most widest part of the first clamping portion 12 and the second clamping portion 22. In one embodiment, the first clamping portion 12 and the second clamping portion 22 are corresponding structures. For example, if the first clamping portion 12 is round in shape, the second clamping portion 22 is also round in shape, and so forth.

In one embodiment, at each of two corresponding sides of the first cushioning body 1, the first cushioning body 1 includes the at least one first assembly portion 11 and the first clamping portion 12 connected to the first assembly portion 11; at each of two corresponding sides of the second cushioning body 2, the second cushioning body 2 includes the at least one second assembly portion 21 and the second clamping portion 22 connected to the second assembly portion 21. The first assembly portion 11 and the first clamping portion 12 jointly form a protrusion, and the second assembly portion 21 and the second clamping portion 22 jointly form a recess. Thus, the first assembly portion 11 and the first clamping portion 12 may be correspondingly assembled with the second assembly portion 21 and the second clamping portion 22, hence allowing the first cushioning body 1 and the second cushioning body 2 to lock and fasten each other and assemble to a required size according to application requirements. Further, each side of the first cushioning body 1 may be provided with the first assembly portion 11 and the first clamping portion 12, and each side of the second cushioning body 2 may be provided with the second assembly portion 21 and the second clamping portion 22. As such, the second assembly portion 21 and the second clamping portion 22 of the second cushioning body 2 may lock and fasten the first assembly portion 11 and the first clamping portion 12 of the first cushioning body 1 to splice into a required size.

Referring to FIG. 1 and FIG. 2, an assembly process of the packaging cushioning structure of the present invention is described in detail below. At the beginning of the assembly process, the first cushioning body 1 and the second cushioning body 2 are separate. Each first assembly portion 11 of the first cushioning body 1 is aligned with and locked into each assembly portion 21 of the second cushioning body 2, and each first clamping portion 12 of the first cushioning body 1 is aligned with and locked into each second clamping portion 22 of the second cushioning body 2, hence securing the first cushioning body 1 and the second cushioning body 2.

The first cushioning body 1 further includes at least one third assembly portion 13 having a configuration direction opposite that of the first assembly portion 11, and at least one third clamping portion 14 connected to the third assembly portion 13.

Referring to FIG. 3 to FIG. 10, in another embodiment of the present invention, the packaging cushioning structure may complete the assembly of the first cushioning body 1 and the second cushioning body 2 further using a fastening member 3. Each of the first assembly portion 11 and the first clamping portion 12 of the first cushioning body 1 as well as the second assembly portion 21 and the second clamping portion 22 of the second cushioning body 2 is recessed pattern. Thus, the fastening member 3 may be locked and fastened in the first assembly portion 11 and the first clamping portion 12 of the first cushioning body 1 as well as the second assembly portion 21 and the second clamping portion 22 of the second cushioning body 2, so as to secure the first cushioning body 1 and the second cushioning body 2. Further, the fastening member 3 may be made of the same cushioning material or plastic material as the first cushioning body 1 and the second cushioning body 2. The fastening member 3 includes an extension portion 31, a first fastening portion 32 and a second fastening portion 33. The first fastening portion 32 and the second fastening portion 33 are extended integrally from two sides of the extension portion 31, respectively. In one embodiment, the extension portion 31 includes a curvature 34 to provide the fastening member 3 with an arched pattern. In another embodiment, between the first fastening portion 32 and the second fastening portion 33 is an included angle 35. The first assembly portion 11, the first clamping portion 12, the second assembly portion 21 and the second clamping portion 22 are adjusted according to the implementation pattern or assembly requirements of the fastening member 3. The included angle 35 may be any angle 35 between 90 degrees and 180 degrees. For example, the fastening member 3 may form a rectangular pattern as shown in FIG. 3, an arched pattern as shown in FIG. 4, or a right-angled pattern as shown in FIG. 5. Further, when installing the fastening member 3, the extension portion 31 is fastened with the first assembly portion 11 and the second assembly portion 21, the first fastening portion 32 is assembled with the first clamping portion 12, and the second fastening portion 33 is assembled with the second clamping portion 22. In one embodiment, the widths of the first fastening portion 32 and the second fastening portion 33 are greater than the width of the extension portion 31, the width of the first clamping portion 12 is greater than the width of the first assembly portion 11, and the width of the second clamping portion 22 is greater than the width of the second assembly portion 21, thereby providing a more steady structure. In one embodiment, the first fastening portion 32 and the second fastening portion 33 are structures corresponding to the first clamping portion 12 and the second clamping portion 22, respectively. For example, if the first fastening portion 32 is round in shape, the first clamping portion 12 is also round in shape, and so forth.

In one embodiment, at each of two corresponding sides of the first cushioning body 1, the first cushioning body 1 includes the at least one first assembly portion 11 and the first clamping portion 12 connected to the first assembly portion 11; at each of two corresponding sides of the second cushioning body 2, the second cushioning body 2 includes the at least one second assembly portion 21 and the second clamping portion 22 connected to the second assembly portion 21. As such, the fastening member 3 is capable of locking and fastening with the first assembly portion 11, the first clamping portion 12, the second assembly portion 21 and the second clamping portion 22, and jointly assembling into a required size according to application requirements. Further, each side of the first cushioning body 1 may be provided with the first assembly portion 11 and the first clamping portion 12, and each side of the second cushioning body 2 may be provided with the second assembly portion 21 and the second clamping portion 22. Thus, the second assembly portion 21 and the second clamping portion 22 of the second cushioning body 2 may respectively correspond with the first assembly portion 11 and the first clamping portion 12 of the first cushioning body 1, and be locked and fastened with the fastening member 3 to splice into a required size.

Again referring to FIG. 6, the assembly process of the packaging cushioning structure of the present invention is to be described in detail. At the beginning of the assembly process, the first cushioning body 1 and the second cushioning body 2 are separate. A user may first place the first assembly portion 11 and the first clamping portion 12 of the first cushioning body 1 to come into contact with the second assembly portion 21 and the second clamping portion 22 of the second cushioning body 2, and then correspond the extension portion 31 of the fastening member 3 with the first clamping portion 12 of the first cushioning body 1 and the second clamping portion 22 of the second cushioning body 2, the first fastening portion 32 to the first assembly portion 11 of the first cushioning body 1, and the second fastening portion 33 to the second assembly portion 21 of the second cushioning body 2. As such, the fastening member 3 is locked and fastened therein to secure the first cushioning body 1 and the second cushioning body 2.

In one embodiment, the first cushioning body 1 further includes a bending line 15, which divides the first cushioning body 1 into a first bending section 16 and a second bending section 17. The first bending section 16 of the first cushioning body 1 includes a first through hole 161. The first through hole 161 is disposed at a position at the first bending section 16 near the bending line 15, and is extended and formed from the bending line 15 towards a direction away from the second bending section 17. The second bending section 17 of the first cushioning body 1 includes a second through hole 171. The second through hole 171 is extended from the bending line 15 towards a direction away from the first bending section 16. Further, the first cushioning body 1 may be bent into the first bending section 16 and the second bending section 17 along the bending line 15, such that the first bending section 16 and the second bending section 17 are overlapped, and the first through hole 161 and the second through hole 171 are also overlapped to jointly form the first assembly portion 11 and the first clamping portion 12. In continuation, the first bending section 16 includes at least one folding lines 18 and 19 to allow the first bending section 16 to be bent along the folding lines 18 and 19 towards the second bending section 17. Further, at a position of the first bending section 16 of the first cushioning body 1 away from the second bending section 17, the first bending section 16 includes the folding line 18, and so the first bending section 16 is allowed to bend along the folding line 18 towards the second bending section 17 to include the first bending section 16 to appear as a right-angled pattern, as shown in FIG. 8. In another embodiment, the first bending section 16 of the first cushioning body 1 includes the folding line 19 near a middle position of the first bending section 16, and so the first bending section 16 is allowed to bend along the folding line 19 towards the second bending section 17 to include the first bending section 16 appear as a right-angled pattern, as shown in FIG. 9. Further, when the first cushioning body 1 is manufactured, the bending line 15 and the folding lines 18 and 19 may be disposed as semi-detached. Thus, the first cushioning body 1 may be bent to form a multilayer structure through the bending line 15 and the folding lines 18 and 19. The second cushioning body 2 of the present invention may also be implemented by the above approach, as shown in FIG. 7.

Again referring to FIG. 6, in one embodiment, the second cushioning body 2 is divided into a third bending section 26 and a fourth bending section 27 by a bending line 25. The second cushioning body 2 further includes a third through hole 261 that is disposed at the third bending section 26 and extended from the bending line 25 towards a direction away from the fourth bending section 27, and a fourth through hole 271 that is disposed at the fourth bending section 27, extended from the bending line 25 towards a direction away from the third bending section 26 and being in communication with the third through hole 261. When the third bending section 26 and the fourth bending section 27 of the second cushioning body 2 are bent along the bending line 25, the third through hole 261 and the fourth through hole 271 form the second assembly portion 21 and the second clamping portion 22.

Referring to FIG. 10A to FIG. 10C, to reinforce the cushioning strength of the packaging cushioning structure of the present invention, a user may bend the first cushioning body 1 into a multilayer structure according to application requirements. The bending process of the first cushioning body 1 of the packaging cushioning structure is described in detail below. At the beginning of the bending process, the first cushioning body 1 appears flat. The user may bend the second bending section 17 along the bending line 15 towards the first bending section 16, such that the second bending section 17 overlaps on the first bending section 16 to form a multilayer structure, and the second through hole 171 and the first through hole 161 are overlapped to form the first assembly portion 11 and the first clamping portion 12, as shown in FIG. 10B. One end of the first bending section 16 away from the second bending section 17 is bent along the folding line 18 towards the second bending section 17, in a way that the first bending section 16 similarly forms a multilayer structure. The first bending section 16 is further bent along the folding line 19 to include the first cushioning body 1 appear as a right-angled pattern, as shown in FIG. 10C.
